ABOUT THE PRODUCT

The Campus® Remote Ethernet eXpress (Campus-REX) RS Interface Card installs into a:

• Campus-Star

Line Unit

• Standalone Campus-RS Desktop Unit

chassis, along with a Campus-RS™ (Rate Selectable)

This comprises half of a High-bit-rate Digital Subscriber Line (HDSL) transmission system. When connected to another Campus-RS, Campus -T1 Campus-768 system can transport digitized voice, data, and v ideo signals over existing copper wire at a number of different HDSL rates.

The Campus HDSL system provides a connection between geographically distributed Ethernet Local Area Networks (LANs) in a campus environment. To provide the connection, the Campus-REX performs transparent 802.3 MAC bridging or static IP routing over an HDSL line. You can use existing telephone-grade copper wiring as the HDSL transmission medium.

, or Campus-E1® Desktop Unit or Line Unit, the Campus-RS

This version of the Campus-REX must be installed in a Campus-RS or Campus-HRS Desktop Unit or with a Campus-RS or Campus-HRS Line Unit. It cannot be installed in an older Campus Desktop Unit or with an older Campus Line Unit.

Campus-REX RS Interface Card U ser Manual 1-1

About the Product

COMPATIBILITY WITH EARLIER CAMPUS

RODUCTS

When mated with a Campus-RS Desktop Unit or Campus-RS Line Unit, the Campus-REX RS Interface Card is compatible, over the HDSL link, with earlier versions of Campus products, such as the Campus-T1, Campus-E1, and Campus-768, as shown in the following illustration. Campus-RS units are not currently compatible with Campus-384 products.

HDSL

Campus-768

Campus-REX T1, Campus-REX E1, or Campus-REX 768

About the Product

All earlier versions of Campus products are manufactured to operate at a single HDSL transmission rate, while the Campus-RS transmission rate is user-selectable. To support compatibility with earlier Campus Products, the following configuration options must be set on th e Cam pus-REX:

• Set the HDSL Operating Mode to Standard Mode.

• Set the Standard Mode HDSL Rate to T1, E1, or 768, to match the rate

of the earlier product.

If a Campus-RS unit is connected over an HDSL link to an earlier Campus product, and if either unit has the HDSL Transceiver (XCVR) Mode set to AUTO, the HDSL link may not operat e properly.

When operating the Campus-RS product with an earlier version of the Campus products, to avoid any problems with link startup or operation, it is recommended that the Transceiver Mode be set as follows:

• Campus-RS = MASTER

• Campus E1/T1/768 = SLAVE

If one or both units are already set to AUTO and the HDSL link is active, disconnect the HDSL link, change the settings as recommended, and reconnect the link. This will assure the link integrity on any subsequent startups.

This situation does not apply to a circuit with two Campus-RS units. You may leave the units set to their default setting of AUTO, and they will operate properly.

For information on setting these options, see “Set the HDSL Operating

Mode” on page 3-7.

Interface card

HDSL

When connecting to another Campus-RS Desktop Unit or Line Unit, Standard Mode is still supported, providing access to HDSL transmission rates of T1, E1 and 768 kbps. In addition, the Campus-RS system can be configured to support an extended set of HDSL transmission rates, over either one or two HDSL loops.

To support these additional transmission rates, set the followin g options on the Campus-REX:

• Set the HDSL Operating Mode to Extended Mode or AutoSync Mode.

Campus-RS Interface card

• Set the Extended Mode Loop Configuration to 1 Loop or 2 Loops,

depending on the physical layout of your HDSL network.

• Set the Extended Mode HDSL Rate to the desired setting.

1-4 Campus-REX RS Interface Card User Manual

About the Product

The range of rates available for the HDSL Rate depends on the setting of the Extended Mode Loop Configuration:

– 1 Loop HDSL Rate settings are between 128 kbps and 1.152 Mbps,

in 64 kbps increments

– 2 Loop HDSL Rate settings are between 256 kbps and 2.304 Mbps,

in 128 kbps increments

Not all of these modes and rates are available if the remote Campus-RS system does not support them. Refer to the remote interface card User Manual to see the HDSL modes and rates supported by the card.

For information on setting these options, see “Set the HDSL Operating

Mode” on page 3-7.

ESTABLISHING AN HDSL LINK

Before an HDSL link can be established in Standard or Extended Mode, the HDSL parameters for both the local and remote units must be set identically.

Using AutoSync Mode allows one unit to determine the HDSL parameters. In AutoSync Mode, one unit is configured as a master and the other as a slave. Upon startup, the HDSL parameters of the master unit are used to establish the HDSL link. No further configuration of the slave unit is required.

If the remote unit is not configured as an AutoSync slave, an AutoSync connection will not be established and the system generates an AutoSync minor alarm. After several failed attempts, the master enters Fallback Mode and attempts to establish a normal HDSL link with the same HDSL parameters. If this is unsuccessful, for ex ample, if the slave un it is configured to a different HDSL Rate, the master unit reverts to attempting to establish an AutoSync connection.

Campus-REX RS Interface Card U ser Manual 1-5

About the Product

APPLICATION

When installed in a Campus-RS Desktop Unit or Campus-Star chassis, the Campus-REX functions as a remote bridge or static IP router.

You can use the Campus-REX to extend subnetworks to remote sites within a campus. Or, for sites separated by greater distances, you can use the Campus-REX to connect them through a public T1/E1 Wide Area Network (WAN). See “Point-to-Point LAN Extension” and “LAN Connections Over

a WAN” on page 1-7 for more information.

Campus-REX software provides complete main bridging tasks of learnin g, forwarding, filtering, and hashing/buffer management, 802.1d Spanning Tree protocol, 802.3 drivers, packet sequencing, segmentation and reassembly, and other local tasks. The Campus-REX is specifically designed for 10BASE-T LANs that use unshielded twisted pair (UTP) segments with reach of more than 100 meters and that require low-cost, high performance connectivity.

The Campus-REX performs full-bandwidth filtering on the 10BASE-T port, and forwarding at the selected transmission rate.

Point-to-Point LAN Extension

As organizations move or change, LANs also evolve and may become fragmented or physically separated. The Campus-REX provid es a lower-cost alternative to other LAN-extension solutions. The Campus-REX provides a built-in 10BASE-T LAN interface that eliminates the need for other internetworking devices while providing 30 times the performance of other sub-rate wireless connectivity options, as shown in the followi ng figure.

1-6 Campus-REX RS Interface Card User Manual

About the Product

LAN Connections Over a WAN

When LANs are distributed over a large physical area (such as within a metropolitan area) or cabling is not available between sites, you can lease appropriate unloaded copper pairs from a local carrier for LAN connectivity. For transport over public networks, you can connect the public T1 network (DSX-1 signal) to the LAN through Desktop Units with CSU/DSX-1 interface cards and the Campus-REX in a Desktop Unit. This app lication, as shown in the following figure, simplifies access to public high-speed WANs for LAN connectivity to remote sites.

Set Up the Campus-REX System

SET THE HDSL OPERATING MODE

The Campus-REX is set to operate in Standard Mode with a T1 (1.544 Mbps) HDSL Rate. This is compatible with other Campus-RS products and with Campus-T1 Desktop Units and Line Units. If this is the desired setting fo r your system, proceed to “Confi gure the Campus-REX as a Bridge or Router”

on page 3-19. Otherwise, follow the steps in this section to adjust the HDSL

transmission rate. There are two ways to configure the HDSL line:

• To use the LCD menus, see “Using the LCD,” below.

• To use an ASCII Terminal, see “Using an ASCII Terminal” on

page 3-11.

Changes to the HDSL operating mode or transmission rate are not automatically made to the remote unit. These changes must be made at both the local and remote units for the HDSL link to be re-established. If the remote unit is not easily accessible, you can follow the instructions in “Logging Onto

a Remote Campus Unit” on page 5-3 to use an ASCII terminal

to perform a remote logon (if an HDSL link is up) and make the desired change. When you change the HDSL settings for the remote unit, the HDSL link is lost; it is re-established when you make the identical change(s) to the local unit.

CONFIGURE THE CAMPUS-REX AS A BRIDGE

OR ROUTER

The Campus-REX can be configured to operate in one of two ways:

• as a bridge to forward 802.3 frames using MAC addresses (see

“Configuring as a Bridge”)

• as a router to forward IP packets based on a static routing table (see

“Configuring as a Router” on page 3-23)

For an overview of bridges, routers, and other network management concepts, see “Internetwo rking and Management Overview” on page 7-1.

Configuring as a Bridge

Two configuration options, described in “MAC-Level Bridging and

Spanning Tree Protocol” on page 7-2, define how the Campus- REX operates

as a bridge. These options:

• set Encapsulation to HDLC or PPP: – Use HDLC for most applications. – Use PPP when the remote unit includes a synchronous interface

card, such as a V.35 card.

• enable or disable Spanning Tree

This section describes how to configure the bridge options for the Campus-REX.

SET THE TIMING SOURCE

The Timing Source option determines the source of circuit timing on the HDSL link. There are two settings for the Timing Source option:

• Internal: Sets the Campus unit to take its timing from an internal oscillator. This is the default setting.

• HDSL: Sets the Campus unit to take its timing from th e H DSL link.

The proper setting of the Timing Source option depends upon the interface card of the remote Campus unit:

• If the Campus-REX is connected to a Campus unit with another Campus-REX RS Interface Card, leave the Timing Source option set to Internal. The Campus system will not operate properly if both units are set to HDSL.

• If the Campus-REX is connected to a Campus unit with a synchronous interface card, such as a Fractional V.35 card, the timing source depends on the setting of the Primary Timing Source option of the remote unit:

– Set the Timing Source to HDSL if the remote unit is set to Internal

or Port.

– Set the Timing Source to Internal if the remote unit is set to HDSL. See the Campus-RS Fractional Interface Card User Manual for

information on the Primary Timing Source option.

• If the Campus-REX is connected to a Campus unit with a Campus CSU/DS-1 or CSU/DSX-1 interface card, leave the Timing Source option set to Internal.

CONFIGURING THE CAMPUS-REX AS A MASTER

OR SLAVE UNIT

The Transceiver Mode option determines the hierarchy of the two Campus units when attempting to establish an HDSL link. There are three settings: Master, Slave and Auto. Master and Slave are available for all three HDSL Operating Mode settings. Auto Mode is only available for Standard and Extended Modes, and is not available for AutoSync Mode.

• If a unit is set to Master, it initiates the HDSL link. The other Campus

unit must be set to Slave or Auto.

• If a unit is set to Slave, it waits for the other Campus unit to initiate the

HDSL link. The other unit must be set to Master or Auto. Slave is the

default setting for AutoSync HDSL Mode.

• If a unit is set to Auto, it automatically switches between Master and

Slave until an HDSL link is established. The setting of the other Campus

unit is irrelevant. Auto is the default setting for Standard and Extended

HDSL Modes.

Unless you have a compelling reason for doing otherwise, leaving the Transceiver Mode option set to Auto is recommended.

CONFIGURING LOOPBACKS

Loopbacks provide a way to test the data communication path between the Campus unit, the remote unit, and the remote host equipment. The Campus-REX supports two types of loopbacks:

• Local to Remote loopbacks test the remote data port, the data path inside

the remote Campus unit, the HDSL line, the HDSL transceivers of both

units, and most of the internal data path inside the local unit. This

loopback does not test the local data port drivers and receivers.

• Remote to Remote loopbacks test the remote data port and a small

portion of the remote interface card.

If both the local and remote units have a Campus-REX interface card, no loopbacks are supported.

CONFIGURING THE CAMPUS-REX AS A MASTER

OR SLAVE UNIT

• If a unit is set to Master, it initiates the HDSL link. The other Campus

unit must be set to Slave or Auto.

• If a unit is set to Slave, it waits for the other Campus unit to initiate the

HDSL link. The other unit must be set to Master or Auto. Slave is the

default setting for AutoSync HDSL Mode.

• If a unit is set to Auto, it automatically switches between Master and

Slave until an HDSL link is established. The setting of the other Campus

unit is irrelevant. Auto is the default setting for Standard and Extended

HDSL Modes.

Unless you have an important reason for doing otherwise, leaving the Transceiver Mode option set to Auto is recommended.

CONFIGURING LOOPBACKS

Loopbacks provide a way to test the data communication path between the Campus unit, the remote unit, and the remote host equipment. Depending on the remote unit, the Campus system supports the following types of loopbacks:

If both the local and remote units have a Campus-REX RS Interface Card, no loopbacks are supported.

• The Local to Local loopback tests the local data port and a small portion

of the Campus-REX RS Interface Card.

• The Local HDSL loopback tests the local data port and the entire data

path of the local Campus-REX RS Interface Card, including the local

HDSL transceiver. The data path in this loopback extends to the HDSL

line transformer, and causes the HDSL link to go down (a Link Alarm

occurs).

• The Remote to Local loopback tests the local data port, the entire data

path inside the local Campus unit, the HDSL line, the HDSL transceivers

of both units, and most of the internal data path inside the remote unit.

5-20 Campus-REX RS Interface Card U ser Manual

Configuring with an ASCII Termi nal

• The Remote to Remote loopback tests the remote data port.

• The Local to Remote loopback tests the remote data port, the entire data

path inside the remote Campus unit, the HDSL line, the HDSL transceivers of both units, and most of the internal data path inside the local unit. This loopback does not test the local data port drivers and receivers.

Once a loopback condition has been initiated, it remains in effect until cleared. You may also set a loopback timeout to clear the loopback automatically after a set period of time has elapsed.

All loopback options are accessed through the Loopback Settings menu. To open this menu:
